聚磷酸铵的制备及阻燃性能测试——介绍一个应用化学综合实验

Preparation and Flame Retardancy Test of Ammonium Polyphosphate:A Comprehensive Applied Chemistry Experiment

介绍了一个聚磷酸铵(APP)的合成、表征及阻燃性能测试的应用化学综合实验。实验内容包括:低温溶剂法制备APP;红外光谱和X射线粉末衍射表征其结构;对APP的溶解度及阻燃性能测试。通过此实验,增强了学生对化学基础知识的理解,有助于提高学生的综合素质,培养了学生的创新思维能力,有利于提高应用化学专业的实验教学质量。

A comprehensive applied chemistry experiment is introduced in this paper,including the synthesis,characterization,and performance of ammonium polyphosphate(APP).This experiment consists of the preparation of APP by low-temperature solvent method,the characterization of APP through Fourier-transform infrared spectroscopy and X-ray diffraction analysis,and the examination of solubility,flame retardancy as well as oxygen index.This experiment can improve students’ability to broaden the basic chemical knowledge and cultivate the critical thinking,which would greatly assist the training of students’solid and comprehensive skills,thus,improving the teaching quality of the applied chemistry major.
